Give new life to your music

Good music becomes great when you hear it through Polk's db Series car speakers. Polk engineers use laser imaging to determine the ideal combination of speaker materials and design to eliminate distortion. The resulting technology produces speakers with smooth frequency response, sharp detail, and the ability to play music at high volumes without strain.

Polk's db651 speakers feature 6-1/2" woofers made from a polymer/mica composite and durable rubber surrounds that won't fall apart under stress from heat, moisture, or time. Liquid-cooled 3/4" silk/polymer dome tweeters use powerful Neodymium magnets to deliver precise high-frequency reproduction, enveloping you in bright musical detail. And you can even pivot the tweeters, aiming them at your ears for improved stereo imaging. The built-in two-way crossovers keep the high and low frequencies flowing to the proper drivers for seamless, efficient audio.

Why replace your car's original speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Mounting Ring: The supplied
mounting ring has mounting holes for both 6-1/2" and 6-3/4" applications,
allowing the speaker to fit more vehicles. In most cases, the ring should be
used to mount the speaker.

Polk db651

If I am comparing these to my stock speakers then they are a good speaker. The polk is a lot more clear and doesn't rattle with bass. I installed these in the front on a Nissan Frontier 2004 truck and the install was not super easy if you don't have experience. Nissan doesn't carry harness extension on the front speaker so you have to splice and use female terminal adapters. You have to use included bracket to screw speaker to car door. It's hard to give these speakers a fair review because I still have the stock radio which doesn't give it enough power, also I haven't compared them to other aftermarket speakers.

Pros:Upgrade over stock speakers

Cons:not an easy install and all parts needed for install not included (nissan frontier 2004)

Disappointed

I have had these speaker in my Saturn Outlook for a couple of years, and I have finally gotten around to tearing them out. Possibly these speakers are a good value for the price paid, but they really aren't wonderful. I was told by Crutchfield that they were recommended because they reproduced better details in the music than other comparable speakers. Unfortunately, they have other major weaknesses such as harsh sound, raspy voices, 'static' like noise from the tweeters, and lack of smoothness. I am running these speakers on a Kenwood dnx890hd head unit and a Clarion XC1410 amp (4x50w). Power is not the problem.

I think that these speakers were my first recommendation from Crutchfield that was bad. Interestingly, I have called back several times for tips on how to make the sound quality better. Each time Crutchfield has insisted that my problem was not the speakers. Though most of the changes Crutchfield recommended has improved the sound, none of them have made the speakers sound good. (I have even resorted to rewiring the speaker from the Amp and that didn't really help). Honestly, I am suspicious as to why so many of the Crutchfield employees are recommending these speakers so much.

I have used Crutchfield on and off for over 20 years. This is the first time I have received truly bad advice.

Pros:Good at reproducing instrumentals in the mid range
Provides a full sound when given enough power (Aftermarket head unit alone will not be sufficient though)
Saturn Outlook is a huge SUV. These speakers are plenty loud.
Bass is adequate.
These speakers are definitely far better than the stock speakers.

Cons:Womens voices are especially raspy. None of the voice reproduction is clean - male or female.
None of the sounds (voice or instrumental) are very smooth
My ears fatigue quite quickly and need to turn them off after a while.
There is a lot of harshness to the sound quality of these speakers

Crutchfield response on Wednesday, January 14, 2015That's a common reaction when replacing car speakers. What you can expect to hear from a new speaker is better clarity and definition in the mids and highs. So your music will sound better and more lifelike, but you might not hear more bass.
The only way to get more bass is to add more power, and if you want to keep the factory radio, that means adding an amplifier. A small (40-50 watts), 4-channel amp can supply twice the power of an aftermarket stereo and three or four times the power of the typical factory radio. That'll improve all the sound, but you'll especially hear it in the fullness of the bass.

Just plain awesome!

These speakers are just plain awesome! Some people spoke of poor bass response. I am getting great sound from mine. Not subwoofer bass, but full range sound. They also have crisp-sounding tweeters. Couldn't be happier with this purchase.

Way better then the bose filth

Didnt fit in any brackets, but i was able to make it work. They sound great! So much more clear then the bose i took out. The highs are great, cant tell with the bass as the bose amp sucks! Id buy them again!

Pros:Crossover!

Cons:Didnt come with connectors to speakers.... Seems dumb not to include those...

Great deal

Installed in 2 pairs in a new car with stock HU so they are limited by a lack of power. They are still a noticeable improvement over the stock speakers. The construction quality seems excellent. My first purchase from Crutchfield and I am very happy. The included install instructions and the wire bracket to attach to the stock wiring was nice to have as I installed these in a leased car.

Pros:Good clarity and range. Great price

Cons:A little too bright for my taste - I feel the same way about Infinity speakers that I have heard - but with an amp and a sub and more eq control I'm sure I would be very happy with the sound.

Good speaker for the price

I upgraded the factory Bose speakers in the front doors of my 2011 Tahoe. I think one of the factory speakers was blown, and they easily distorted at higher volume. The Polk's were definitely an improvement, although not as major as I had expected. Good highs/mids, not a ton of bass (which I didn't expect from a speaker in this price range). Fast shipping from Crutchfield. Included instructions weren't bad, but I'd recommend doing some Internet research on pulling your door panels if you're not familiar with doing it.

Bought for Rear Ext Cab in Silverado

I bought these for the rear of my 2007 NBS Silverado Ext Cab. Little tweaking with the bracket and install was complete. Sound is fantastic. Much better than stock. The clarity and detail is great. Makes you go through your music selection again to hear the new details. I put the DB6501 up front and these in the back. I listen to mostly metal, hard rock, and blues and these handle it all with ease. No shrill, no loss of mid, just a great all around speaker. If you are on the fence, just buy these.

Sound Great!

Installed these in the rear doors of my '09 Subaru Forester (paired with DB651S in the front and powered by 22 watt JVC head unit) and they sound so much better than the stock factory speakers. I put them through their paces with a variety of music from driving drums and bass to intricate instrumentals to subtle vocals. Everything sounded tremendous, although I did detect some buzziness when I boosted the bass level on the EQ. However, this may be a result of my installation - I'll check it in the coming days - as I installed the rear doors first before I was completely confident of what I was doing.

Pros:Great sound reproduction. Well made. Fit vehicle well. Efficient (produce much more sound than factory speakers at the same volume level).

Fantastic sound

The Polk speakers recommended by the experts at Crutchfield did a great job assisting me with the upgrade. I used the Polk speakers as an upgrade from the factory Bose speakers and I couldn't be more pleased. These speakers were a definite upgrade from what I had previously in my Tahoe. The sound is much more complete and the fit was good as well. Great speakers !

Pros:Great fit with minimal work during the install. Very full sound across all frequencies. Well built speakers that should last a long time.

Cons:Some reworking had to be done to fit these into my rear door cutouts. Small plastic tabs on the door had to be ground off with a Dremel tool. This only took a few minutes to correctly place the speakers into the rear doors.

Super Loud and Clean

I installed these speakers in the front doors of my 2010 chevy silverado extended cab and they were perfect. They are super loud and very clean and crisp sounding. You can hear clearly from about 10 feet outside of the truck when my stock radio is turned up all the way. They don't have great bass, but it certainly isn't bad.

Polk Db651

2nd time I have bought from Crutchfield. Installed in rear door of 2005 Nissan Frontier. Pretty straight forward, did have to drill out the mounting plate holes as they were way to small to get the speaker screws started straight. Also had to extend the bottom mounting whole a quarter of inch to match factory door mount. Any way speakers sound great! Bass for classic rock hits pretty hard. Powered by a 25watt JVC head unit I bought last year. Was going to get amp and sub next year but might not have too. Can hardly wait to hear speakers once they are broken in, since I have heard they sound better after a several hour breakin.

Pros:Sound is great for classic rock. Bass was much better them expected when I listened to Boston's More Than A Feeling. Also sounds great when playing the 1812 Overture.

Cons:Mounting bracket had to be drilled, speed clips provided by Polk had to be removed in order to fit in factory mount.

Factory speaker upgrade

My 2011 Silverado 2500HD came with a Bose Audio System. You would think that if Bose was going to put their name on something and maybe introduce someone that has never heard any of their product before, they would want to do a lot better than this. After upgrading the front speakers to the Polks there was definitely an improvement. Brighter and smoother top end and a little less distortion at louder levels. But not a significant change.

Pros:Better high frequency response than the factory speaker. Less distortion.

Cons:Not worth the cost and labor. Looks like to get the improvement I expected I'll have to revamp the whole system.

Let the music flow.

Both the Polk Audio db651 & db651s sound great with my stock 2006 GMC Sierra Crew Cab truck radio. As expected the radio volume is turned up just a bit as the speakers use more amps. My design criteria was to replace speakers and have a clearer sound. The base is adequate for my ears that are north of age 50. Now I'm back to cleaning & detailing the truck.

Okay

These sound okay but could be better. Maybe because it's only 6.5"? I got these to replace my 6x9's because the tech guys at Crutchfield told me that aftermarket 6x9's will not fit. I would have to get 6.5" with adapter plate. Well, I tried that and they fit but the sound size is very small compared to my stock 6x9's, so I returned these speakers back to Crutchfield. I did some sizing up and had bought some Polk 6x9 speakers. The tech was right that they didn't fit but, all I needed is an adapter ring for the 6x9. And guess where I found one? I used my stock Toyota 6x9 speakers and removed the cone and installed the new aftermarket 6x9 into the Toyota adapter. WaLa! It fit perfectly! And it sounds great too! I don't know why I haven't seen any tech forums suggesting this. It was so easy! Plus, I didn't need a wiring harness; I just soldered some new speaker wires onto the existing Toyota connector. Can you say plug and play?

Pros:If you have a Toyota Tacoma you can use an aftermarket 6x9's as long as you reuse the Toyota adapter.

Great speakers

The db651 is a nice speaker. Very smooth highs with no harshness and ample bass--it really moves some air. Sound MUCH better than VW Jetta MKVI factory speakers. I had the Polk DXi series installed in a different car with a different head unit. They were nice too, but I like the db series better. The DXi series seemed too sharp on the high end. Not the case with these.

Pros:Smooth highs. You can adjust the tweeter.

Cons:None with the speakers themselves.
If you are installing in a VW Jetta Mk VI, the speakers will be a good 1.5" away from the door panel--Crutchfield doesn't supply a spacer like the factory speakers have, so some of your sound will get lost behind the door panel. Crutchfield has no installation instructions for the Jetta MKVI either. Really? The top selling VW car? Come on, Crutchfield.

Awesome, fits 2012 Wrangler Unlimited soundbar

Written By Tony T, Military Base on Saturday, October 05, 2013

On Crutchfield, 2012 Jeep JKU says db651s fits sound bar and 651 does not. This is incorrect. The DB651 does indeed fit, but you have get rid of the stock grill cover and use the polk ones. I did this, and painted it matte black, and it looked stock

Simply Amazing!

Finished installing these earlier today, and I already love them! They replaced an older set of Polk's that had been driven hard for eight years and finally wore out, (model db650, bought here from Crutchfield back in 2005). These newer db651's are everything I hoped they would be. I have a 12-inch subwoofer, so I was unconcerned from the start about whether these Polks had good bass or not. Using the head unit's high-pass filter, I cut off frequencies below 80Hz to these Polks. Just love the warm tweeters! Marvelous! I absolutely love these Polks! The warmth of the tweeters is the very reason I bought db's a second time.

Pros:Clear and warm sound quality. Absolutely delightful!

Cons:Crutchfield's fit guide does not appear to be entirely accurate for my vehicle. I installed these in a 2003 Dodge Dakota club-cab. Fit-guide says these don't fit in the front door location. I think this might be true if attempting to re-use the Dodge factory bracket, which make the speakers protrude out approx. ¾-inch from the door's sheet metal, but it is not necessary to use the Dodge bracket. You can use the included Polk bracket or the Crutchfield supplied Scoche bracket and mount direct

Distinct improvement over stock

I replaced the last two of the rear stock speakers with these and the sound stage definitely sounded so much more improved. Vocal sound really nice and I can hear words I had never heard with the stock. String instruments definitely sound much better. Bass is not the best, but I do not expect much since I need to add a subwoofer for that.

Pros:Better vocals, string instruments; great price and look very sturdy and well made.

Crisp

I was a little hesitant on buying these as I figured crutchfield was just trying to sell polk and I was looking at another name brand but went ahead and ordered these. They came several days later and I installed them in my denali which was super easy. The music that came out was nice, crisp and clear so I am happy to have them. I have a factory amp and these speakers come alive. As everyone else has said if you want bass then add subs which I did and the polks complement the entire sound system. If you want great highs mixed with mids then buy these polk speakers you cant go wrong.

Excellent Speakers

Recently I purchased a 2011 GMC Sierra truck. Unfortunately the stock speakers were so poor all music was muted and muddy. I knew Crutchfield could solve my problem and did so with the Polk db651 pair of 6 1/2 inch speakers that I installed in both doors. Highs are beautiful, mids are clear so the song words can be understood and the bass is nice and tight.

Pros:Installation instructions and all necessary hardware to install the speakers included. Nothing was left to guess at!

Outstanding Speakers

Written By Derrick, NJ on Wednesday, June 19, 2013

Great sounding speakers for the money! At first i didnt like the amount of bass that they produced and was a little worried about it. Then roughly 1 month later they completely blow me away!! Alot of people seem to not know about a speakers break in time to really shine you need at least 80 to 100 hours of break in time and within that period do not turn them up past 3/4 of the volume if it is connected to a head unit and 1/2 way if connected to an amplifier. Trust me it is well worth the wait!!!!

Pros:Best 6.5 speakers for the money!!! Deep satisfying bass around 50hz and the mids are clean and highs are on the flat note (unlike infinity) which is the kind of sound i prefer!

Polk Audio db651

Great speaker and a significant upgrade to the sound. Did not fit the door, or the supplied adaptor kit. I would have had to use the speaker adapter to mount it on the separate adapter kit and that would have had to be modified to fit the car door I wound up modifying the original speaker/mount and attaching the speakers directly to that

Pros:Great sound. Decent price

Cons:Did not fit, supplied mount adapters did not fit. Took some energy to adapt original speaker/mount

like em

I got these along with the shallows. The site said that they would only fit up front. I took a chance and got the shallows for the back doors and was also able to get the adapters and wire kits. Sound is an upgrade. If u want bass get sub to go along. Not bad set of speakers though.

Fantastic!!

I installed these in my 2011 Chevy Silverado 2500HD Crew Cab. The speaker adapters and speaker wire harness connectors Crutchfield provides makes the job so incredibly easy! The master instruction guide from Crutchfield is awesome. Took me longer to take the door panels off then it did to install the speakers. The difference between stock speakers and these polks cannot even be compared. So much better! Also, I have a Alpine amp pushing these and they can handle every bit of power you feed them.

Polk Audio db651

Great. Even marine grade. they have built in tweeters so if you looking for bass this isn't them. If you want to upgrade to a nice stereo these are great mids and high speakers. They are very loud and crisp.

Good Speakers at a decent price

Written By Ed, Boston, MA on Monday, February 18, 2013

One of my factory installed speakers died in my almost 9 year old truck. So I had them all replaced & professionally installed with these speakers. They sound great. I am not an audiophile but they sound 100x better than my original truck factory speakers...They fact that they are paired up with my none factory Sony explod head unit makes a huge difference..

Polk Audio db651

bought these polks to replace the factory speakers in my new kia soul. the difference is night and day, the polks handle everything the factory stereo can dish out. they sound great, good bass response clean highs, nice speakers.

Pros:great sounding speaker. if you can follow instructions and have basic tools its easy.

Cons:rear speaker bracket did'nt work with these speakers, mounting holes exceeded the diameter of the bracket.

Polk Audio db651

I recently purchased a 2005 GMC Serria 1500 Crew Cab and the door speakers were shot. I decided to replace them with the Polk Audio db651 speakers and I couldn't be happier with my choice. The installation was fairly easy and the adaptors included made the speaker wire connections a snap. Just be sure to watch the video on YouTube first to make getting the door panels off eaiser. If you're not handy with a drill and figuring out how to adapt the front speakers to fit, you might want to get a friend to help. The speakers sounded a little flat at first but after a few days they sounded great. Good bass, midrange and treble. If the CD player in my stock radio wasn't broken I wouldn't change it. That will be my next project and I'll probably come back to Crutchfield for that.

Great Speakers

I got these to go with my JVC head unit in my truck and they sound great. I've had a lot of good experience with Polk DB speakers in the past and these were even better than I thought. I was expecting the bass to be non-existent or very weak, but they are very well rounded and actually thump a little depending on the music. (Your results may vary...it may just be my truck door cavity carries the low notes better than other car doors.) Of course the highs and mids are very good, which is pretty much a given for most Polk speakers and why I chose these in the first place. I bought some pioneer 6.5" speakers for half the price of the Polks to put in the rear just for fill and they sound crappy compared with the Polks. If I had to do it again I would probably get another pair of Polks for the rear, but oh well. That's what you get for trying to save money. Overall they are a great sounding co-axial speaker and worth the price. They are probably about as good as it gets for this configuration unless you step up to component speakerI would highly recommend them to anyone looking for a well performing speaker in this price range.

Pros:Great sound, well rounded, good value for the price

Cons:Don't like the grille cover design, but I didn't need them as they are behind the factory door panel screens anyway
